in asp.net mvc project using localhost instead .\sqlexpress in connection string - asp.net

I installed Sql Server Express but I need to use localhost as Datasource in connection string.
Here is the connection string now:
<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS.../>
I want to use like this:
<add name="DefaultConnection" connectionString="Data Source=localhost
Is there a way to use localhost alias instead of ".\sqlexpress" in connection string. I work in a team project and the other people use connection string like that (they have installed sql server - not express)

You have to mention only localhost and database name like below
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=localhost;Initial Catalog=DatabaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
</connectionStrings>

Connection string using local SQL Server

How to write the connection string to local SQL Server database using web.config?
Here is my connection string in web.config. But when I open local/demo, it said:
login failed for user ''.
Actually I'm using Windows authentication, so I thought it doesn't need user and password.
<connectionStrings>
<add name="HRISContext"
connectionString="data source=.;initial catalog=BPSDEMO;Pooling=false;persist security info=True;user id=;password=;MultipleActiveResultSets=True;App=EntityFramework"
providerName="System.Data.SqlClient" />
</connectionStrings>
If you want to use Windows authentication, then yes, you must not include any user id and pwd in your connection string - just remove those completely. But you must include the Integrated Security=SSPI setting instead.
Try this:
<connectionStrings>
<add name="HRISContext"
connectionString="data source=.;initial catalog=BPSDEMO;Integrated Security=SSPI;MultipleActiveResultSets=True;Pooling=false;persist security info=True;App=EntityFramework"
providerName="System.Data.SqlClient" />
</connectionStrings>

Can only open 2 concurrent sql connections (asp.net VB)

I have a very complex data structure within a web application that im working on, which requires 3 connections at once to a MSSQL database, id rather not but its the only way to achieve what is required for now.
I set my connectionstrings in web.config as such:
<connectionStrings>
<add name="Foo_mainConnectionString1" connectionString="Data Source=GDE-WK-003\SQLEXPRESS;Initial Catalog=Foo_main;Integrated Security=True" providerName="System.Data.SqlClient" />
<add name="Foo_mainConnectionString2" connectionString="Data Source=GDE-WK-003\SQLEXPRESS;Initial Catalog=Foo_main;Integrated Security=True" providerName="System.Data.SqlClient" />
<add name="Foo_mainConnectionString3" connectionString="Data Source=GDE-WK-003\SQLEXPRESS;Initial Catalog=Another_FOO;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
When set up as above (2 connections to the same DB) it works fine (although the third ' Another_FOO' is an unused one from a discontinued part of the project.
So in order to get another connection established, i changed "Another_FOO" to "Foo_Main"
Giving me 3 connections to the same DB.
On trying to run the website, it now seems that none of the connections are established.
Any ideas why this might be? Is there likely to be a connection limit that i cant find?

ASP.net aspnetdb.mdf connection string

After configuring the Membership Provider, I noticed that there is no connection string for ASPNETDB.mdf in my web.config. Shouldn't there be a connection string? What is the appropriate syntax? Thanks in advance!
The default connection string is defined in machine.config:
<add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>

ASP.NET System.Data.EntityClient connection string help

I'm running ASP.NET MVC on a shared server and I'm having problems connecting to SQL via System.Data.EntityClient. Below is the connection string that my hosing provider gave me to connect to SQL and the one that VS configured for my local machine during development, what should my connection string look like when I deploy to the server?
From my hosting provider:
<add name="WeddingsDBEntities"
connectionString="data Source=<server name>; Initial Catalog=<db name>; User ID=<user ID>; Password=<password>;"
providerName="System.Data.EntityClient"/>
From VS (during development):
connectionString="metadata=res://*/Models.WeddingsModel.csdl|res://*/Models.WeddingsModel.ssdl|res://*/Models.WeddingsModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\WeddingsDB.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient"
Thanks!
You have to wrap the connection string instide an entity connection string which is in the format of
<add name="Name"
connectionString="metadata=<Conceptual Model>|<Store Model>|<Mapping Model>;
provider=<Underlying Connection Provider>;
provider connection string="<Underlying ConnectionString>""
providerName="System.Data.EntityClient"/>
Instead of:
<add name="WeddingsDBEntities"
connectionString="data Source=<server name>; Initial Catalog=<db name>; User ID=<user ID>; Password=<password>;"
providerName="System.Data.EntityClient"/>
Use this:
<add name="WeddingsDBEntities"
connectionString="metadata=res://*/Models.WeddingsModel.csdl|res://*/Models.WeddingsModel.ssdl|res://*/Models.WeddingsModel.msl;provider=System.Data.SqlClient;provider connection string="data Source=<server name>; Initial Catalog=<db name>; User ID=<user ID>; Password=<password>;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient"/>
Change the provider from entityclient to sqlclient (assume code first EF).
providerName="System.Data.EntityClient" />
to
providerName="System.Data.SqlClient" />
<add name="Name" connectionString="metadata=res://*; provider=System.Data.SqlClient; provider connection string='; data source=YOURIP;Initial Catalog=YOURDB;Persist Security Info=True;User ID=YOURUSER;Password=YOURPASSWORD; Connect Timeout=15;Encrypt=False;Packet Size=4096;MultipleActiveResultSets=True'"
providerName="System.Data.EntityClient"/>
Hope this Will help you!!
